CD338, known as ABCG2 (BCRP1), is a multi-drug resistance (MDR) family protein that is a member of ATP binding cassette (ABC) transporters. It is highly expressed on primitive ‘side population’ (SP) stem cells. This SP phenotype is based on the efflux of fluorescent dyes such as Rhodamine 123 and Hoechst 33342. The SP cells express low or undetectable levels of CD34.  In the bone marrow, about 0.05% population of cells displays the low fluorescence and are highly enriched for repopulating cells.  The highest levels of BCRP1 mRNA expression have been seen in KDR+ human stem cells.  The expression of ABCG2 appears to be highly conserved as it has been identified in various species.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 2.0 µg per 106 cells in 100 µl volume or 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

* Pacific Blue™ has a maximum emission of 455 nm when it is excited at 405 nm. Prior to using Pacific Blue™ conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome.
